Last month, a project took the last female and relocated her into the territory of the remaining male as part of a 20-year recovery plan for the species, one of the world’s largest and rarest frogs that exists on just two Caribbean islands, Montserrat and Dominica.
The two frogs are the island’s only known survivors of an outbreak of the deadly chytrid fungus disease, a pandemic ravaging amphibian populations worldwide. There are less than 100 left in the wild.
The frogs were living 700m apart among the boulders of a steep, fast-flowing stream in the rainforest at a site known as Fairy Walk. The male had been heard calling for several weeks but after 10 nights of hour-long hikes to the site, the team of conservationists was getting worried that they hadn’t found the female.
Eventually one of the local field workers spotted her. “She was just sat there at the side of the stream, it was absolutely amazing and such a relief,” said Jeff Dawson, amphibian program manager for the Durrell Wildlife Conservation Trust and coordinator of the mountain chicken recovery program, which also involves ZSL, Chester zoo, Nordens Ark in Sweden and local governments.
The female was then caught, weighed and measured, and checked for general health, before being taken to the male’s location downstream and placed in a “soft release” tent to give her time to get used to the new environment. The male joined her about an hour later, and the sides of the tent were gradually opened to allow them to move out in their own time. “When we left you could hear contact calls which was really encouraging,” Dawson said.
Zoologists and camera traps will continue to monitor the frogs in coming weeks, as one of the fears is that the female will try to return to her former site. But Dawson said the abundance of natural and artificial nest holes, a constant water supply and plenty of food meant they were unlikely to move.

Advocates push for stronger regulation of Fourth of July shows to protect bay ecosystem
On July 4, all around San Francisco Bay, brightly colored fireworks will light up the night sky. It’s a fun tradition. But how much does the rockets’ red glare pollute the bay?

Fireworks are often set off over water, as they are in the shows around San Francisco Bay, because setting them off over land creates a risk of fire. However, fireworks can cause so much pollution, some communities ban them over lakes used as drinking water sources.
Following two fireworks shows over San Francisco Bay earlier this year, held as part of the festivities celebrating the 50th Super Bowl, several reports of fireworks pollution came in to Baykeeper’s Pollution Hotline.
The morning after the first fireworks display, swimmers in the water at San Francisco’s Aquatic Park swam into significant plastic and cardboard debris. That day, National Park Service staff removed charred fuses, plastic, and cardboard pieces from the Aquatic Park beach, filling four 50-gallon trash containers.
Following the second fireworks show a week later on February 5, 30 more pounds of fireworks debris washed up at the Aquatic Park beach. More continued to wash up for weeks. It’s likely that even more remained in the bay, washed up on other shorelines, or washed out into the Pacific Ocean.

In addition to the debris that is often left behind following displays, studies have linked fireworks to water contamination, particularly by perchlorate, a chemical used in fireworks to create bright flashes of light. Perchlorate exposure can cause thyroid problems, and is considered a “likely human carcinogen” by the US Environmental Protection Agency. It can also harm wildlife.
This pollution doesn’t have to happen. There are methods of preventing, or at least minimizing, pollution from fireworks. Some cities are already doing this. In San Diego, for example, companies putting on fireworks displays are required to use practices that give maximum protection to the body of water below.
In San Francisco, as in other cities around the country, there are several simple ways to reduce pollution. To start, companies putting on fireworks displays should remove all cardboard, plastic, and other debris from the water and shorelines within 24 hours of the show to minimize impacts on marine life and swimmers in the water.

Environmentalists respond by criticizing closed-door trade deals that favor corporations
The other shoe has finally dropped regarding the controversial Keystone XL pipeline project, and it’s a big one. TransCanada is suing the United States for $15 billion for rejecting the pipeline project that would have carried crude oil from Canada’s Alberta tar stands to refineries on the Gulf Coast.

Last week, the Canadian company filed an arbitration claim under the North American Free Trade Agreement (NAFTA) over President Obama’s rejection of the pipeline, making good on its January threat to take legal action against the US decision.
According to the official request for arbitration, the $15 billion tab is supposed to help the company recover costs and damages that it suffered “as a result of the US administration’s breach of its NAFTA obligations.” NAFTA is a comprehensive trade agreement between the United States, Canada, and Mexico that went into effect in January 1, 1994. Under the agreement, businesses can challenge governments over investment disputes.
In addition, the company filed a suit in US Federal Court in Houston, Texas in January asserting that the Obama Administration exceeded the power granted by the US Constitution in denying the project.
Keystone XL is a 1,179-mile pipeline system that, if approved and constructed, would transport up to 830,000 barrels of tar sands crude oil from Hardisty, Alberta across the border into Nebraska eventually travelling down to refineries on the Gulf of Mexico. The project saw opposition from a broad range of groups including landowners in Texas and farmers in Nebraska as well as national environmental and indigenous rights groups.
President Obama had rejected the pipeline proposal on November 6, 2015 on the grounds that transporting crude oil from Canada wouldn’t help the US economy or increase the country’s energy security.
In response to this latest salvo from TransCanada, a coalition of environmental groups, including 350.org, Sierra Club, Natural Resources Defense Council, and Bold Alliance came out swinging at a press conference on Monday. They not only disputed TransCanada’s claims, but also turned the tables, using the NAFTA challenge as ammunition in the growing fight against the latest international trade agreement, the Trans-Pacific Partnership.
“This lawsuit from TransCanada is both absurd and a perfect illustration of why it is people around the world feel that elites are getting out of touch. The rejection of the Keystone XL pipeline …more
New peace deal with the country’s largest insurgent group, FARC, offers hope of a reprieve
Colombia’s national parks were created as both a showcase for the country’s spectacular biodiversity and as a protected refuge for its delicate ecosystems. But in recent years, they have instead become a haven for criminal activities that are leaving a trail of environmental devastation.
Colombia is one of the world’s 17 most biodiverse countries. Due to the great variation in altitudes and climates within the country — from high mountains to pristine white sand beaches — this South American nation is home to many rich and varied ecosystems. Its 314 types of ecosystems host nearly 10 percent of the planet’s biodiversity. Worldwide, it ranks first in bird and orchid species diversity and second in plants, butterflies, freshwater fishes, and amphibians.
Nowhere is this rich and complex array of life more evident than in its network of 59 national parks, which span snow-capped mountains of the Andes, the Amazon rainforests, coastal cloud forests, open savannas and the Caribbean islands. These parks hold within them archaeological treasures, uncontacted indigenous tribes, endangered flora and fauna, such as jaguars, cotton-topped tamarins, and spectacles bears, black cedar, and Colombian palm, and (perhaps unfortunately) a wealth of mineral resources.

However, the parks are also home to guerrilla insurgents and criminalized paramilitary groups that have been drawn to the wilds by the lucrative prospect of exploiting coca crops and cocaine production and illegal mining and logging. The invasion of these underworld networks has been accompanied by ecological destruction and contamination that threatens the future of some of Colombia’s most fragile protected areas.
“It is a confluence of illegal forces and groups that profit from these activities,” says Elsy de Alcalá, advisor to the leadership board of Parques Naturales Nacionales (PNN), the government body that oversees the country’s national parks. “These could be the most critical problems we face in our parks.”
The most visible of these criminal activities is the cultivation of coca, the base ingredient for cocaine. Eight percent of the coca grown in Colombia has been planted on 5,457 hectares of land in 16 national parks, according to the most recent coca survey by the United Nations Office on Drugs …more
Councilmembers cite strong concerns about public health and safety
The Oakland City Council took a strong stand against coal last night. Following a long and often emotional city council meeting — during which whistles and cheers were at times met with boos and yelling — the council passed an ordinance prohibiting the storage and handling of coal and petcoke at Oakland facilities, and a resolution that would specifically apply the ordinance to the Oakland Bulk and Oversized Terminal (OBOT), which is being built on the old Oakland Army Base.

The meeting drew hundreds of impassioned Oakland residents, including representatives from the labor, faith, environmental, and health communities, as well as the terminal developers. Those speaking against the terminal emphasized that West Oakland already suffers the effects of disproportionate air pollution. They argued that added particulate pollution tied to the coal export terminal could elevate the risk of health problems like asthma, cancer, and lung and heart disease.
Several speakers also pointed to climate change and it’s impact both globally and in Oakland. “There is strong evidence that if coal is not shipped from OBOT, it will not be shipped and combusted at all,” Linda Rudolph, director of the Climate Change and Public Health Project at the Public Health Institute, said, speaking to the city council prior to the vote. “If coal is shipped from OBOT, the greenhouse gas emissions from burning that coal will be greater than that from all five bay area oil refineries. It will contribute significantly to climate change and climate change is the defining health challenge of this century. It’s a serious threat to the health of Oakland residents.”
Those speaking on behalf of the project said that measures could be taken to mitigate the impacts from coal and emphasized the jobs associated with the terminal project. “[The terminal] will be the source of generational prosperity for many of the… un- and underemployed residents, and most important, it will be safe,” said Jerry Bridges, president and CEO of Terminal Logistics Solutions, which will operate OBOT. (Labor representatives, however, spoke out strongly against the use of the terminal for coal shipments, rejecting the idea that the issue is one of jobs versus community health or justice, and pointing out that the terminal will create jobs regardless of the specific commodities shipped through it.)
The buildup to the vote has been considerable. Oakland residents and activists have …more
Plant’s closure follows more than half-a-century of sustained citizen action against nuclear energy in California
The story behind the Pacific Gas and Electric Company’s (PG&E) announcement last week that it would close down the Diablo Canyon Nuclear Power Plant is the culmination of a 60-year land conservation and appropriate energy debate between the utility company and the people of California. The point winner is the environmental community and grassroots activists who fought long and hard for the plant’s closure.

PG&E’s concession that it cannot afford to continue running the last operating nuclear plant in California effectively brings to an end this state’s more than half-a-century long contentious relationship with nuclear power.
Back in the 1950s the utility company had sought to prove the economics of the emerging nuclear technology as “too cheap to meter” and received the first commercial nuclear power plant license in the United States. The company’s then president, Norman Sutherland, envisioned “atomic parks” along the California coast in Sonoma, Mendocino, Santa Cruz, and San Luis Obispo counties, that would produce enough energy to replace fossil fuels and hydro-power — an idea that was vociferously opposed by many Californians.
Conservationists, focused on protecting the California coast as open space, challenged the atomic parks as a threat to the environment. Fishermen feared the parks would lead to loss of fisheries. Dairy farmers worried about radiation impacting milk production. Thus, a diverse group of citizens came together and organized a campaign to get state and federal agencies to stop licensing nuclear plants. The debate expanded to concerns about the safety of nuclear power, the unresolved issue of waste disposal, and a desire for clean decentralized alternative energy generation.
The Bodega Bay Atomic Park was stopped while under construction when an earthquake fault was discovered under the proposed location of the nuclear plant's reactor. Bodega Head is now a state park. PG&E withdrew plans for atomic parks in other locations when faced with massive opposition and ever-recurring discoveries of earthquake faults adjacent to planned reactor sites. Diablo Canyon was the only large nuclear plant the utility finally constructed, though in the face of stiff opposition. A remarkable cast of characters challenged the licensing of the facility in public meetings, courts, mass rallies, and civil disobedience actions, and continued to press for its shut down …more
Study first to show that harmful chemicals from natural gas operations are contaminating bodies of Pavillion, Wyoming residents
Many of the toxic chemicals escaping from fracking and natural gas processing sites and storage facilities may be present in much higher concentrations in the bodies of people living or working near such sites, new research has shown.

In a first-of-its-kind study combining air-monitoring methods with new biomonitoring techniques, researchers detected volatile organic compounds (VOCs) released from natural gas operations in Pavillion, Wyoming in the bodies of nearby residents at levels that were as much as 10 times that of the national averages.
Some of these VOCs such as benzene and toluene are linked to chronic diseases like cancer and reproductive and developmental disorders. Others are associated with respiratory problems, headaches, nosebleeds, and skin rashes.
“Many of those chemicals were present in the participants’ bodies at concentrations far exceeding background averages in the US population,” notes the study, titled “When the Wind Blows: Tracking Toxic Chemicals in Gas Fields and Impacted Communities,” which was released last week.
Some residents of Pavillion have for years been concerned about the rise in health issues that they suspected were connected to emissions from the gas production activities. This tiny town of less than 250 people has been at the center of the growing debate on fracking since 2008 when locals began complaining that their drinking water had acquired a foul taste and odor back in 2008.
In 2014, air monitoring data showed some toxic chemical emissions at oil and gas sites in Wyoming were up to 7,000 times the “safe” levels set by US federal environmental and health agencies. In March of this year, Stanford University researchers found evidence that fracking operations near Pavillion were contaminating the local groundwater.
Now this new study, conducted by researchers with the national environmental health organization Coming Clean, establishes clearly that at least some of these harmful chemicals are making their way into the bodies of nearby residents.
The study focused on measuring ambient levels of a specific family of VOCs named BTEX chemicals — which include benzene, toluene, ethylbenzene, and xylenes — because these chemicals are known to be hazardous to human health even at low levels. Researchers then used new biomonitoring methods to detect these chemicals in 11 local residents who volunteered to …more
